SEED CLEANER AND PURlFlER.

SPECIFICATION forming part of Letters Patent No. 583.996, dated June 8, 1897.

Application filed December 26, 1895. Serial No. 573,402. (No model.)

To call whom it may concern.-

Be itlrnown that I, THOMAS J. HATFIELD, a citizen of the United States, and a resident of Dublin, in the county of YVayne and State of Indiana, have invented certain new and useful Improvements in Seed Cleaners and Puritiers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters and numerals of reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is an elevation showing a side view of the device complete externally. Fig. 2 is a vertical longitudinal sectional view showing the internal arrangements of the working parts. Fig. 3 is a closedend slotted bar with, a lug in upon its upper end. Fig. 4 is an open-end slotted hanging bar.

This invention has relation to certain new and useful improvements in grain and seed cleaners, and more particularly in that class of such machines as described and claimed in my pending application, Serial No. 524,612.

The object of the present invention is to provide a machine of this character which is simple in its construction and operation, which can be easily and rapidly operated, and which is strong and reliable in its parts.

With this and other objects in view the invention consists in the novel construction and combination of parts, all as hereinafte'i described, and pointed out in the appended claim.

Referring to the accompanying drawings, the letters Z designate the main frame.

E is an upright post on either side of the mill, resting upon the cross-ties to which the ends of the fan-shaft are journaled, the drivewheel being secured to the outer side of one of these upright posts, as shown in Fig. 1. The opposite ends of the fan-shaft are supplied with small cog-wheels with eccentricpins for attaching the pitman. The fan and driving-wheel are made in the usual way.

Dis the fan-drum, with extended arms, which are secured to the inner sides of the main frame as a casing. The hopper A is seend of the shoe to the other.

cured to the frame in the same manner, one end resting upon the drum.

B is the chaffing-shoe, which is provided with a chaff-screen I, the inner end resting upon a shelf, the outer upon a rod. The chalf-outlet is shown at the letter d.

In Fig. 2, c in O is an adjustable bottom forming a grain-chute and air-chamber, the lower end held with screws in the sides of the casing. The upper end, being loose, rests upon buttons 19, by manipulating which the outer end of the bottom is raised or lowered to any desired degree. I) is an air-board for regulating and controlling the air-blast from the fan.

F is the lower shoe, which is provided with a short purifying-screen II, removable, the inner end resting upon a bench or shelf, the outer or tail upon a rod extending from one side of the mill to the other side, one end of said rod being provided with a nut, the other with a thumb-screw. tended to hold the upper part of the mill more securely together. This rod also holds the purifying-screen securely in place.

The numerals III and IV in the shoe F designate removable screens extending from one This shoe is provided with a solid bottom, as shown at V. The forward end of the shoeF is held in place between the frame by means of two hangers h, one on either side, which are bolted to the sides of the frame-tie Z and secured by clips onto the wooden hanger-piece G, which is attached to the sides of the shoe. The lower or discharge end of the shoe moves upon two small wheels, secured to the inner sides of the short legs Z. The pitman is connected at its outer end with the upper end of the hanging bar h. The hanging bar j is secured at the top end to the sides of the upper chaffing-shoe by means of clips and bolts, and near its center it is similarly secured to the stationaryextended arms of the drum. Its

lower end is slotted, as in Fig. 4. This slot fits over the lug 03, (shown in Fig. 3,) which is a slotted piece of iron secured to the sides of the lower shoe F by means of headed bolts, secured with nuts on the inner side, which, when loosened, permits the slotted piece to be raised or lowered, so that the lug operat- This rod is also ining in the slotted hanger gives a longer or shorter stroke to the movement of the upper and lower shoes, which are controlled by the h anging bar.

The object of this hanger is to receive and discharge at its lower end the larger grain, which is not intended to pass beyond the short purifyingscreen II, butto empty over the tail of this screen into the mouth of the hanger and out intomeasuresunderneath the mill.

' end of the short purifying-screen II.

The grain is fed into the mill in the usual way through the hopper, which is provided with a slide operated by means of the handle a. From the hopper it falls onto the inner end of the chafing-screen, which is supplied with a strong air-blast from underneath which carries the chaff, the, over the tail of the screen, discharging it at (Z. The grain falls through this screen into themouth of the chute G (shown in Fig. 2) onto the bottom of the grain-board c and is carried downward to the lower end, where it passes onto the inner Here the smaller grains pass through this screen,

fallin g upon the lower or long dividing- 1 screens, while thelarger grain discharges over the tail of this pu rif yin g-screen in to the men th of the grainhanger ll, whence it is discharged into measures. The larger grain which has fallen onto the dividing-screen III passes down and is'discharged at the tail 2, as shown in Fig. 2. The smaller grain passes through this screen onto number IV, the'larger grains being discharged over the tail at 8. lhe Last and smallest grain passes through this screen. falling onto the solid bottom of the shoe F. and is discharged at 4:, as shown, thus separating, purifying, and dividing the grain into four separate and independent receptacles as it passes through the hopper, following the darts in Fig. 2 until itis finally discharged, as shown. 7

llavin g thus described my invention in detail, what I claim as new, and desire to secure by Letters Patent, is-

In a grain-separator, the combination with the upper and lower screen shoes connected by an oscillating rod pivoted to the fan drum. its upper end being secured to the upper shoe 'by a clip and the lower end. slotted to engage a pin projecting from a plate which is secured to the lower shoe; the said plate being provided with a slot, whereby the same may no adjusted vertically, of a vertical rod pivoted to the main frameof the separator, and having
